Oh, the politics is wonderful - I so want my PM to be Vetinari and the head of the Met to be Vimes. And Granny Weatherwax to be the power behind the throne. King Verence is a portrait of Charles, really, isn't he?
Love the Vimes 'boots' theory of general economic injustice: poor people can only afford rubbishy boots which wear out. And have to put up with using cardboard when the soles have gone. And eventually get enough money together to buy another pair of boots. Over a lifetime, spending a huge proportion of income on 100s of pairs of crappy boots that wear out. Aristrocrats like Lady Sybil inherit classy, handmade boots which last for several lifetimes...
